There are 70 apps accessing my Facebook account. I did not know that before I had MyPermissions scan my account. With this free app for iPhone or for Android, you can keep track of the apps that have access to your various online profiles, including Facebook, Twitter, Google, Yahoo, Dropbox, Instagram, Foursquare, and Flickr. The app doesn't do anything that you can't do directly on the permissions page of a given account, but it acts as a convenient dashboard to monitor and control which apps have access to your accounts.

To check the permissions of one of your accounts, you must sign in to the account via MyPermissions. Right up front on the app's FAQ page, it states "we do not save any personally identifiable information, nor do we save your credentials or passwords." In fact, all the app is doing is passing your off to the permissions page of each of your online accounts. Sometimes this results in a less-than-ideal page layout on an iPhone (Twitter, for example), but it's still easy to go down the list and approve or revoke the permission of the apps accessing that account.

The app was recently updated so that you receive alerts when a new app begins accessing one of your accounts. I've been using the app for a few days now, and I've not received any notifications. When I launch the app, however, it's easy to see how many apps are accessing each of my accounts and how many new apps are accessing my account. For each account listed, you'll see two buttons: Apps and Alerts. Tap the Apps button to go to the permissions page of a given account to see all of apps that have been granted permission to access it. Tap the Alerts button to get a pop-up window within the MyPermissions app to see the apps you've yet to review. If the entire list looks good, you'll find a convenient Trust All button at the bottom.
